Oscillations about an Equilibrium Position01:04

Oscillations about an Equilibrium Position

5.6K
Stability is an important concept in oscillation. If an equilibrium point is stable, a slight disturbance of an object that is initially at the stable equilibrium point will cause the object to oscillate around that point. For an unstable equilibrium point, if the object is disturbed slightly, it will not return to the equilibrium point. There are three conditions for equilibrium points—stable, unstable, and half-stable. A half-stable equilibrium point is also unstable, but is named so...

Forced Oscillations

6.7K
When an oscillator is forced with a periodic driving force, the motion may seem chaotic. The motions of such oscillators are known as transients. After the transients die out, the oscillator reaches a steady state, where the motion is periodic, and the displacement is determined.

Damped Oscillations

6.0K
In the real world, oscillations seldom follow true simple harmonic motion. A system that continues its motion indefinitely without losing its amplitude is termed undamped. However, friction of some sort usually dampens the motion, so it fades away or needs more force to continue. For example, a guitar string stops oscillating a few seconds after being plucked. Similarly, one must continually push a swing to keep a child swinging on a playground.
Although friction and other non-conservative...

¹H NMR: Interpreting Distorted and Overlapping Signals

1.1K
Spin systems where the difference in chemical shifts of the coupled nuclei is greater than ten times J are called first-order spin systems. These nuclei are weakly coupled, and their chemical shifts and coupling constant can generally be estimated from the well-separated signals in the spectrum.
As Δν decreases and the signals move closer, the doublets appear increasingly distorted. The intensities of the inner lines increase at the cost of those of the outer lines as the signals are...

Types of Damping

6.7K
If the amount of damping in a system is gradually increased, the period and frequency start to become affected because damping opposes, and hence slows, the back and forth motion (the net force is smaller in both directions). If there is a very large amount of damping, the system does not even oscillate; instead, it slowly moves toward equilibrium. In brief, an overdamped system moves slowly towards equilibrium, whereas an underdamped system moves quickly to equilibrium but will oscillate about...

Oscillations In An LC Circuit01:30

Oscillations In An LC Circuit

2.5K
An idealized LC circuit of zero resistance can oscillate without any source of emf by shifting the energy stored in the circuit between the electric and magnetic fields. In such an LC circuit, if the capacitor contains a charge q before the switch is closed, then all the energy of the circuit is initially stored in the electric field of the capacitor. This energy is given by

Summary

Neuronal oscillations possess a non-zero mean, suggesting their amplitude modulation contributes to evoked responses. This finding integrates ongoing brain activity and stimulus-evoked signals, crucial for understanding cognitive processes.

Area of Science:

  • Neuroscience
  • Computational Neuroscience
  • Electrophysiology

Background:

  • Neuronal activity is broadly categorized into ongoing oscillations and evoked responses, typically studied independently.
  • A potential unifying mechanism suggests that oscillations with a non-zero mean could explain evoked responses through amplitude modulation.

Purpose of the Study:

  • To investigate if neuronal oscillations exhibit a non-zero mean.
  • To determine if amplitude modulation of these oscillations contributes to evoked responses.
  • To explore the biophysical basis of non-zero oscillatory means and their implications for electrophysiological data analysis.

Main Methods:

  • Utilized computational modeling with a biophysical neuron network model.
  • Analyzed electroencephalography (EEG) data from 90 participants (young and elderly).
  • Employed spatio-spectral decomposition and simulations of coupled oscillators.

Main Results:

  • Biophysical models demonstrated asymmetric intracellular currents leading to non-zero mean alpha oscillations across varied parameters.
  • Empirical EEG data revealed non-zero mean alpha oscillations in 93% of participants.
  • Simulations indicated spatial synchronization can mask oscillation modulation but not baseline shifts.

Conclusions:

  • Non-zero mean oscillations provide a mechanism linking ongoing and evoked neuronal activity.
  • Amplitude modulation of oscillations likely contributes to evoked response generation.
  • Future research on cognitive states, aging, and neuropathology should incorporate oscillatory dynamics.
